I believe these are the latest Centers for Disease Control pregnancy/abortion statistics: http://www.cdc.gov/nchs/pressroom/04facts/pregestimates.htm. The highlights for the year 2000: 4 million live births, 1.3 million induced abortions, 1 million fetal losses/miscarriages. Over the 1990-2000 decade, the pregnancy rate dropped by 6% and the abortion rate dropped by about 20%.
